Lewis, 29, posted some adorably cute pictures of him and his girl in the Italian city and The Hamptons, on his Twitter profile on Monday.

The Formula 1 star accompanied the snaps with the caption: "Better late than never. @nicolescherzy & I in Venice for our 6th Anniversary. #goodtimes #godisthegreatest (sic)."

He then added another collage of photos taken from their time in New York, which he captioned: "Then The Hamptons New York. Always wanted to go after watching "White Chicks"! We had an amazing time. @nicolescherzy (sic)."

The pair seem very much in love since rekindling their relationship in March following a split in July 2013. The duo flew to Capri in Italy last year with their bulldog, Roscoe, to celebrate their fifth anniversary.

Lewis and Nicole, 35, marked the occasion by taking a romantic helicopter ride over the gorgeous island before spending the weekend holidaying on the beach with their pet pooch.
